    Do sharks sleep?

    They do sleep, although not in the same way humans do.

    Most sharks need to swim constantly to ensure water passes through their gills so obviously they are unable to stop and sleep.

    However they have rest periods where their brain activity is a lot less than usual but is still enough to continue swimming.
